It is well known that in automobiles glass panes are employed, particularly with the so-called closed type of bodies, toslide into and out of pockets in the car frame or in a door frame, and when out of the rame are guided along grooves which are lined p with felt or similar material both to prevent j rattling and to prevent the entry of dust and dirt when the `pane is in the closed or raised position. It has been Afound, however, even with the y that the pane will vibrate and rattle within its frame.

The present invention provides a means oi' eliminatingthis rattle, and consists primarily in a friction member which forces the pane into tight contact with the felt at one side of each of the guide grooves. yA spring is em loyed to maintain the member in such rictional .and forcing relation with the pane, and clamps are provided whereby the device may be quickly positioned and removed: and whereby the `distance of the axis of the roller from the clamp, i. e., from the walls of the pocket, 3 may beimmediately and accurately adjusted. The device is composed of very few parts, is neat in appearance, has its operative elements substantially protected from the weather, and is of very slight 'incumbrance upon the vehicle. Owing` to its construction, it is adjustable so that in being positioned, it is brought automatically to fit a great variety of window and door frames.

With these and other purposes in view as will appear in the course of the following specification taken in conjunction with the accompanying drawings, there are shown on the drawings:

`Figure 1, a perspective view of the device from the glass pane has an inwardly extend- 100 as appliedV to a door frame;

Fig. 2 is a longitudinalV cross-section through the device of Fig.,1. j j

Fig. 2 is a section on linel2-2a of Fig. 2.

Fig. 3 is a side elevation partly in section of a modified form of the device.

Fig. 3 is an end view of the upper part' of the device of Fig. 3.

In Fig. 1, the body 10 of the vehicle is conventionally represented as having a door hinged thereto in any suitable manner not use of such elt strips,

shown. This door has a lower pocket with the upstanding posts 11, 12 thereon, respectively, at the outer and innersides of the door. The door pocket with its walls 13 and 14 at the` outside and inside defines the opening 15 in which the glass pane P slides.

Theposts 11, 12 define a groove 18 whichv has the felt packing 17, 18 at the two sides thereof, in packing relation to the glass ane P.v

The anti-rattling device of the present invention `comprises a clamp member 2O l which has its downwardly extending finger 20L engaged against the inner face of the inner wall 14 'of the pocket, and an outer clamping member 21 having a downwardly extending linger 21a which engages over the customary bead or roll 22 adjacent the upper edge of the wall 14. These two fingers 20,

21a therefore cooperate to hold the device itself in a detachable but rigid position opposite the center of the glass rpane P. `The two clamping'inembers`20, 21 are lmounted on a threaded sleeve 23: The member 20 has a threaded portion 24 to engage this sleeve, while the member 21 has an aperture 25 for. the loose reception of the sleeve 23. It will be understood that as the sleeve 23 is rotated 'within the portion 24, the position'of the pivotpin 26, hereinafter more clearly described, will be varied with relation to the clamping lingers 20, 21, and therefore with relation'to the distance of its axis from the walls 131, 14 ofthe pocket. lA lock nut 27 is likewise lengaged upon the threaded sleeve 23 to jam the portion 24 and hold it in a predetermined Aand ,definite relation to the sleeve 23. A clamping nut 28 islikewise provided to force theloose clamping member 21 into engagement with the outer face of the door wall'14, whereby the door wall is tightlyV clamped between the fingers 20, 21a.

The end of the threaded sleeve 23 away ing flange 29 providing an aperture coaxial with the sleeve itself. A plunger 30` has a threaded end passing through this aperture and cooperating with a nut 31 on the exterior of the sleeve to form a stop to regulate los the amount of movement of the plunger 30 toward the glass pane. At the other end the plunger 30 has a collar 32 and extends asbifurcated parallel members 33 which support the pivot pin 26 `01E the riction'roller llo 3st. This friction roller is preferably made of fiber or similar material to prevent scratching the glass pane. rlhe forwardly extended walls of the sleeve 23 are similarly cut out by a gash for the reception of the roller 34, and furnish a positive guide to preventl the rotation ol the plunger 30 within the hollow sleeve 23, as shown in Fig. 2".

In operation, the clamping linger 20 is slipped into position with the lock nut 27, the other clamp 2l and the clamping nut 28 loosenedor removed. The sleeve 23 is then rotated until the friction roller 34C is in a suitable frictional contact with the glass pane 1G, and the pivot pin 26 thereof is in position at right angles to the line of movement of the pane P. For this, the friction roller 3l should be engaged :forcibly with` the pane so that it exerts a thrustalong the plunger 30 toward the right in Fig. 2, with a resultant compression of the spring 35 which is compressed between the collar 32 and the ilange 29 of the sleeve. If desired, the nut 31 may be turned up to regulate the initial tension upon the spring The lock nut 27 is now screwed tightly against the portion 24 of the clamp 20 to retain the latter rigidly with regard to the sleeve 23. The second clamp 2l is now brought tightly into position on its respective side of the wall la, and the clamping nut 28 screwed home so as to hold the clamp 20, 2l tightly and rigidly applied to the upper edge of the door pocket wall 14.

As the pane is raised or lowered, the friction roller 34 forces it outward against the felt 17 at the side shown. It will be understood that a similar felt-ed groove is provided at the outer edge of the pane P in the customary manner, and that it is similarly brought into play. It the pane P does not move truly in its guides, the roller 34 will give and take under the action of its spring 35 so that at all times an' outward position is given to the pane P, whereby rattles and other etiects of free vibration are eliminated from this part of the vehicle.

The device may be quickly and easily removed by reverse operation, by loosening the nut 2S, so that the clamp 21 is liberated, whereupon the device may be rocked out of position.

IVhen the pane P has retreated completely within 4the pocket 15, the roller 34 is of course disengaged but is prevented from lying out of the assemblage along with the plunger 30 by reason of the stop nut 31 on the plunger.

In the modified form of Fig. 3, most of the elements are as already described, but the lock nut 3l on the end of the plunger 30 has been replaced by arcotter pin 40 which is passed through the diametrical slot in the adjacent end oit the threaded sleeve 23, and thus serves to maintain the plunger 30 against rotation within the sleeve 23. In this form ot execution, the sleeve terminates short of the roller 3G, and only the bifurcated ends 33 ot' the plunger 30 project toward the glass pane.

The method ot employing this device is the same as that of the form of Fig. 2.

It is obvious that the invention is not limited to the specific modifications shown, but that it may be modilied in any wise within the scope ot' the appended claims.
